' GONCAVING HEELS.

Application filed May 10,

My invention relates to a heel concaving machine adapted to impart a tapering concavity to the top of the heel.

It is my object to provide a safe and accurate tapering heel concaving mechanism adapted to impart with great accuracythe exact taper desired to the concavity of a heel used in such shoes known as arch preserver shoes. These heels it is my object to mount in a moving heel clamp of such predetermined form that by reason if its cooperation with the guides in my machine the exact concavity and taper will be imparted to each heel of a given lot so that accurate fit'will be insured between the heel and the rest of the arch preserver shoe, while at the same time securing great rapidity of production with the minimum of skill necessary on the part of the Operator and with the maximum safety for the operator.

It is my further object to provide a machine which is universal with respect to different sizes of heels. It is an additional object to provide a machine that requires the minimum of judgment on the part of the operator and will only necessitate two simple movements on the part of the Operator so that unskilled labor can be largely utilized and the factor of skill and judgment substantially eliminated, thereby economizing on labor costs and making it possible to produce heels in large quantities, of great accuracy, with workmen or workwomen of substantially no experience.

Referring to the drawings,

Fig. 1 is a top plan view of the machine with the heel about to be concaved;

Fig. 2 is a top plan view of a portion of the machine showing the heel holder in its This frame carries a series of journal brackets '3 in which is journaled the cutter shaf 4. The cutter shaft carries the cutter 5 on the end thereof which cutter is provided with the usual teeth 6. The cutter shaft is 1927. Serial Jim-190,335.

driven by the belt 7 from. the pulley 8 mounted on the armature shaft 9 of the'motor 10. This cutter is adapted to project through a slot 11in a pivoted cutter table 12 pivoted at 13 between the set screws 15 carried in the bracket 16 on the table 12. This table 12 has mounted thereon a pair of spaced guides 14 held in position by the clamping screws 17 mounted on bolts in the slots 18 of the pivoted table 12. The table itself is adjusted in position by the set screw 19. I

Between these guides 14 and guided thereby is the heel clamp and holder which consistsof a pair'of clamping arms 20 pivoted at 21. The arms are actuatedthrougha handle 22 mounted adjacent their pivot. The arms are connected together by anadjusting clamping'plate 23 which is pivoted at 24 on one arm and extends over the other arm where a slot in the plate designated 25 is engaged by a setscrew 26 and a wing nut 27 carried by the clamping arm which is overlapped by the plate 23. Each of these arms are cut away as at 28 to permit the cutter to pass up through between the arms to engage with the heel 29. This heel is positioned by T shaped stops designated 30 which engage the forward edge of the heel and the sides thereof; The inner ends of the T shaped stops, as at 31, extend beyond the arms 20 but above the level of the table 12 so that the cutter can rotate beneath said extensions 31 without coming in contact with them; It is apparent that the hell holder is so arrranged as toposition the heel and hold 90 it in position to beconcaved while at'the same time the holder is adjustable to varying sizes and types of heels.

These arms 20 have their upper faces in? clined so that the heel is held at an incline withthe result thatthe' concavity 32 "on the top ofthe heel will have its bottom 33 tapered, the bottom being of greater depth at the front Of the heel than at the rear thereof. The arms of the holder are provided with two guidingsurfaces, a relatively long surface 35 and a relatively short surface 3 1 at an angle to one another. In-addition to this a stop 36 is provided for limiting the movement, away from the operator, of the holder. This stop is adjustable.

Operation.

The operator takes the heel and places it so that what is normally the top of the heel now is placed in the bottom position because the heel is inverted. The forward edge of the heel is placed against the T shaped overhanging portions 31 while the holder is then moved so that its side- '34 is against one guide 14 and its longer opposite side '35 is against-the other guide. The operator grasps the handle and pushes the holder slowly forward over the cutter so that the. material is cut away from the cutter with the desired concavity and taper. The

holder is then withdrawn and its position is altered in that the side 35 of the holder which fori'nerly engaged the guide 13 is moved awayfrom that guide so that only its side 34 engages with the guide. Accordingly the other guideis now engaged by the side 35 and is disengaged from the side '34 of that arm of the holder- This spaces the heelvat a different. angle to the, cutter and it is again 'moved with the holder into cutting position for the completion of the concavity and the taper.v 7

By these two simple operations of pushing the heel forward andwback again and the simple clamping of the heel in the holder, am enabled to provide a mechanism that vwill give a'perfe ct concavity and taper of predetermined size to-the heels without the exercise of any particular ingenuity, experience 'or skill on the part of the operator. If the operator is supplied with a group of heels of different kinds, with the proper holder or the proper taper, and 'withethe guides adjusted by a fOrema'n, the ordinary work-man; or workwom'an can perform "this delicate 'operation 'with substantial-lyno ex.- perience, skill or instruction, and with the utmost safety as the operator has no-occasion for coming in engagement with the cutteror going nearjthe, butter. The movement of the holder is limited by "the adjustable stop. 36'.

It will be :imderstood "that I desire to comprehend within", my invention such modifie'ationsas may. bernecessary to adapt it to varying conditions and uses. Having thus fully described my invention, what I claim "as new and desire to se cure by Letters Patenhfis-z 1. In a heel concaving'machine, 'a-su-pporte ingplatform, a cutter rotating therethrough,
